Abstract
A blow-molded drum body has a cover fitted over this neck and provided with an outer wall with a shoulder clamped against a connecting ring affixed to the body during the blow-molding thereof. The T-section ring has an upper flange overlapped by the cover and a lower flange which is thicker than its upper body so that a clamping ring fitting over the shoulder and the web of the connecting ring can bear upon the overlapping region of the outer wall of the cover and hence indirectly upon the upper flange, but directly upon the lower flange.
